1. 环境说明：
ORACLE 版本：10.2.0.1 RAC
裸设备无ASM

2. GG安装目录必须是共享磁盘。
格式化共享磁盘挂载于第一节点。

3. 在源端建立GOLDENGATE用户。
源端：

SQL> create user goldengate identified by goldengate default tablespace goldengate;

User created.

SQL> grant dba to goldengate;

Grant succeeded.

目标端：

SQL> create user goldengate identified by goldengate default tablespace goldengate;

User created.

SQL> grant dba to goldengate;

Grant succeeded.

4. 创建GOLDENGATE所需目录。
源端：
